JSP not working

I have installed Tomcat 4.1.18 successfully on Windows XP Pro. I run the startup.bat in my apache\bin directory and when I key in http://localhost:8080, I get the start page. However, when I try to bring up my JSP page, it is not working.
<html>
<body>
<% out.println ("testing JSP"); %>
<h1>JSP test</h1><br><hr>
</body>
</html>
Any idea why this is not working? I see the "JSP test" fine, however the "testing JSP" doesn't show up which means the URL is valid. I have intentionally made typos in the out.println and it has been ignored. Thanks in advance.

Ray,
How do you determine that your JSP page is not working? If you see "JSP Test" from your jsp page that means it is working at least partially up to this line.

Irene,
I would expect the HTML page to display "testing JSP" followed by "JSP test". I am only seeing the latter which is in HTML, but the output from the scriptlet is nowhere to be seen. Thanks.

Can you get the JSP examples that come with Tomcat working?

numguess.jsp is working.

I found my problem - I must not have set the classpath correctly. Thanks for everybody's help.
